I have a tseng labs et4000 video card (isa), running on a 486 with freedos beta 6 and msdos 5. Basically, it leaves little lines about 5mm long and about 1mm high all over the screen in some programs. There is nothing wrong with the card itself. I think I need a dos driver for this card. Can anybody help? Thanks.

I'm not so sure that your card would need a DOS driver. I'm running the same or similar chip integrated on my board, Tseng Labs ET4000/W32, and have never needed anything special for MS-DOS 6.22. Possibly a Freedos problem? If you have ruled out any kind of failure for the card or the monitor, perhaps you're picking up 'interference' (crosstalk) from another card, the power supply or even a source external to the computer. You might try moving the card to another slot, if possible. The only vid drivers that I'd ever needed were for Win3.1 and Win95. I don't think Tseng provides support for their older products, but you *might* try looking at the various driver sites such as: http://www.driverguide.com Still, the Freedos beta would be my 'suspect'. Do you know how much video ram the card has, can it be changed/replaced? hth

Just to backup jboy's point here, I have an IBM PSValuepoint 486 that has onboard ET4000 video. the video runs fine with DOS 6.22 or DR-DOS 7.03.

Nah, i'm sure it's not freedos, because the exact same thing happens with msdos 5. I think it may be motherboard settings or something, because I fiddled with some bios settings which improved it (though only slightly). I'll try another slot, etc.

This is not very likely, but is there a place either in the bios or on the video card for selecting interlaced or non interlaced monitors? Is the right one selected? When you are booting, if you go into the bios are the lines present? This would eliminate DOS being the problem? What about DOS video drivers you don't need? Are you installing any video drivers in the config.sys including ANSI.SYS?
